Stethojulis interrupta (One-line Rainbowfish / Cutribbon Wrasse)

Family: Labridae

Distribution: The marine One-Line Rainbowfish, Cutribbon or Brokenline Wrasse (another fish of many aliases) lives on the coastal to outer reef regions in Japan and Australia in areas of mixed sand, rock and coral.  They live to about 20m depth in small schools.

PH: 8.1 – 8.4

Temperature: 23°C (73 F) – 26°C (79F)

Salinity: 1.020 – 1.025

Description: The Cutribbon Wrasse grow up to 13cm in length.  True to its name, it has an interrupted mid-lateral stripe running from snout to below the eye.  A mixture of yellow, salmon pink, pale silver-blue and dark tones makes this another beauty in the marine world.

Diet: As with all wrasses, Stethojulis interrupta is carnivorous and will take frozen and live offerings.  In the wild, they eat by sorting small animals through mouthfuls of sand, so it is best to mimic this in your tank.  Provide such tasty treats as fireworms, clams, mysid shrimp, squid, flaked foods, tubeworms, flatworms, scallop clam and other small crustacean.

Breeding:

Like other wrasse, Stethojulis interrupta can change sex during their life to maintain the balance of dominance in a harem, which consists of a dominant male and multiple females in their natural marine environment.  The females release their eggs into the water and the ocean currents take them away.  As such, they are notoriously difficult to breed in captivity.

Comments:

Stethojulis interrupta has been known to be semi-aggressive and is recommended for moderate to expert aquarists.  Decorate your marine aquarium with rockwork, a fine, thick layered sandy base and caves in which to hide.  Allow for both high light levels and shaded areas.  It can frighten easily so provide a lot of hiding places and a deep sand bed so that it can retreat when needed.  You will need a medium to large tank to hold this species as it loves deep water and plenty of room in which to swim; at least 113 litres (30 gallons).

Remember that this species may not be reef safe, so exercise necessary caution.

Recommended Compatible Species:

Cutribbon Wrasse can be cantankerous so you will need to bear this in mind when choosing tankmates.  In the wild, it has been found alone and in small groups, so more than one individual is only necessary to bring out colouration and activity.

Depending on the size and temperament of your wrasse, potential tankmates could include the hogfish, parrotfish, pseudochromis, squirrelfish, puffers, tangs and surgeons, and live corals.
